If you have an electron gas, which consist of just electrons, and you would control the axis of the spin of all the electrons, would the amount of inertia needed change. Some of the old vacuum tubes I believe had electron gas, plus a high magnetic field like in a MRI would be needed to control the spin of the axis of the electrons. So if this could all be put together and rotate the electrons gas through 360 degrees from pole to pole and back would the amount of inertia needed vary???

Gyroscope’s unexplained acceleration may be due to modified inertia.
When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why.

The Tajmar effect.
Martin Tajmar – Gravitomagnetism Research | Wiki
Following the work of Podkletnov, physicist Martin Tajmar, a professor of space propulsion studies at Dresden University of Technology, produced anomalous inertial effects (generation of small amounts of thrust or momentum) by spinning superconductive tori, as well as spinning superfluid helium. In the experiments performed by Tajmar and his research team, spinning superconductive rings and superfluid helium (both at a temperature of 4 kelvins), produced an acceleration in a laser gyroscope positioned above the apparatus (but not in direct contact with the apparatus). That is to say, the laser gyroscope itself experienced a minute acceleration in the same direction of rotation of the spinning superconductive discs (gyroscopes are used to detect accelerations and changes in orientation)
Interestingly, the effect only occurred when the superconductors and liquid helium were spinning in a clockwise direction, but not counter-clockwise. Tajmar has theorized that in the Southern hemisphere the counter-clockwise direction should produce an acceleration in the laser gyroscope in the direction of rotation of the apparatus while no similar acceleration will be observed for the clockwise direction of rotation, as occurs in the Northern Hemisphere. This is an important detail, as it is absolutely consistent with Haramein’s amendment of Einstein’s field equations where torque and Coriolis effects are considered. Tajmar’s experiment therefore confirms that the structure of spacetime has Coriolis dynamics present due to fundamental torque as the result of a gradient in the vacuum energy density producing the gyroscopic rotational effects of a body, such as the earth.
Although the effect is small — with an acceleration on the order of 3 +/- 1.2 x 10-8 times the acceleration of the ring in the clockwise direction — it is pointing to effects beyond Newtonian-based thrust production that can potentially be utilized for advanced propulsion and inertial modulation technologies. Moreover, Tajmar has shown the same anomalous acceleration effects not only in niobium rings, but aluminum and stainless steel as well, leading him to posit that the effect may be a result primarily of the spinning superfluid helium used to cool the materials to 4 kelvins. Further testing may result in a mechanism for advanced space propulsion using propellant-less drives.
The Tajmar experiments and positive results therein can be regarded, indirectly, as an independent verification of Podkletnov’s experiments demonstrating that gravitational modulation and inertial effects can be achieved by spinning toroidal magnetic and electric fields.

“Rather than microwaves, the experiments to validate McCulloch’s theory will use light with one experiment traveling in a loop and another with a laser bouncing off asymmetrical mirrors.”popularmechanics.com/space/rockets/a24219132/darpa-emdrive/

I'm worried, but that is the rule of science.
At least he set a new standard on what should be done to confirm EmDrive&co

Forces claimed by potential propellantless propulsion systems like the Mach-Effect thruster or the EMDrive are in the µN or even sub-µN range. In this paper, an automated thrust balance design capable of measuring forces of 100 nN for thrusters with a maximum mass of 10 kg is described to test these claims. The torsion balance features an electromagnetic calibration method, adjustable magnetic damping and tilt control as well as electromagnetic shielding. All onboard electronics can be controlled wirelessly via an infrared module for serial communication. Power is supplied to the balance using three separate liquid metal feedthroughs: one for voltages up to 500 V and frequencies up to 200 kHz, one for high voltage up to 30 kV DC or AC, and one for high frequency signals up to 3 GHz. The thruster can be rotated by 180° to measure three different thrust directions without breaking the vacuum and changing the setup in order to gain confidence and refute e.g. thermal drifts. The whole balance is controlled via a script language implemented in LabVIEW. We tested Mach-Effect thrusters provided by Woodward and our own built model exploring higher frequencies and mixed-signals that are believed to create significantly higher thrusters. Also a magnetostrictive version was built and tested. For the EMDrive, several different frequencies and setups (with/without dielectric insert, flat/spherical end caps) were tested. So far, only thermal drifts and no real thrust has been observed in all our measurements.

Propellantless propulsion is believed to be the best option for interstellar travel. However, photon rockets or solar sails have thrusts so low that maybe only nano-scaled spacecraft may reach the next star within our lifetime using very high-power laser beams. Since 2012, a dedicated breakthrough propulsion physics group was founded at the Institute of Aerospace Engineering at TU Dresden to investigate different concepts based on non-classical/revolutionary propulsion ideas that claim to be at least an order of magnitude more efficient in producing thrust compared to photon rockets. Most of these schemes rely on modifying the inertial mass, which in turn could lead to a new propellantless propulsion method. Our intention is to develop an excellent research infrastructure to test new ideas and measure thrusts and/or artefacts with high confidence to determine if a concept works and if it does how to scale it up. At present, we are focusing on two possible revolutionary concepts: The EMDrive and the Mach-Effect Thruster. The first concept uses microwaves in a truncated cone-shaped cavity that is claimed to produce thrust. Although it is not clear on which theoretical basis this can work, several experimental tests have been reported in the literature, which warrants a closer examination. We are building several models of different sizes to understand scaling laws and the interaction with the test environment. The second concept is theoretically much better understood and is believed to generate mass fluctuations in a piezo-crystal stack that creates non-zero time-averaged thrusts. Apart from theoretical models, we are testing and building several such thrusters in novel setups to further investigate their thrust capability. In addition, we are performing side-experiments to investigate other experimental areas that may be promising for revolutionary propulsion. To improve our testing capabilities, several cutting-edge thrust balances are under development to compare thrust measurements in different measurement setups to gain confidence and to identify experimental artefacts.

"The alternative is if the EM-Drive proves to give even higher thrust levels as higher microwave cavity Q-factors are achieved. Then high acceleration, at 1 gee levels, become reasonable. But can we adequately shield against the proton barrage of the Interstellar Medium as we approach the speed of light? Magnetic fields may afford some protection, but we’ll need massive shielding to absorb any x-rays produced by the medium as it is violently thrust aside via our fields. Interstellar dust will pack a punch, thus precursor shields that smash the dust into ions will be needed and will need constant replacing. Is smashing around close to lightspeed worth it?"

A Chinese television propaganda piece that the english title claims to describe the EMdrive propellentless drive project. It appears they have or will very soon attempt to put the EMdrive into space in a satellite. The piece does not make the technical or other aspects explicit.

They are indicating that they are making progress at the same pace as developed countries for communication satellites.

However, the level of “developed country effort” is not clear because EMdrive is widely believed to be impossible physics....

Part I.

This paper reports on experimental investigations of a recently proposed and still speculative class of spacecraft propulsion using a closed resonant microwave cavity to produce thrust, with no conventional expulsion of reaction mass, and claimed to operate via several unconventional interpretations of physics.Such a device would have remarkable applications for spacecraft propulsion, but positive experimental results to date, while suggestive, are near the limits of state of the art measurement resolution and subject to significant confounding errors due to thermal drifts and other subtle effects. The most prominent of these experimental results are those of White et. al. from NASA Johnson Space Center. We report on the fabrication and vacuum testing of both a replica of White’s experimental configuration as well as a cavity and driving microwave circuit of our own design, with careful attention to maximizing driving RF power and cavity resonant quality factor Q in both the NASA and NRL cavity geometries. No attempt is made to independently explore new physics in this paper; efforts are limited to experimental measurement of forces generated by these cavities and characterization of errors due to thermal drift, magnetic dipole coupling,
electromagnetic interference and RF leakage to the surrounding vacuum chamber structure, and other effects. The objective of this work is to rigorously weed out potential false positive thrust signals with null and control experiments, creating a trusted baseline dataset for later theoretical inquiry if merited. All test results will be reported, whether positive or null.
